For my Glo at least, this firmware version seems to have fixed the long-standing problem where the first page of the book shown after waking the device from sleep would be displayed with very light text, which would then darken to normal after the page was turned.

Also new is that it is now refreshing properly after using the dictionary, highlighting text, etc. (Edit: By properly I mean it is doing a full refresh. Before it did a parial refresh where the popups had been, which left the screen looking blotchy because the text under the popups was darker than the rest.)
